Matt Damon stars in the upcoming HBO Liberace biopic "Behind the Candelabra" and the actor talked in a recent interview about the amount of nudity required for the role and what it was like kissing co-star Michael Douglas.

"Normally I'd say no to nudity, but I just did a lot of it playing the long-term partner of Liberace, Scott Thorson, in 'Behind the Candelabra,'" Damon said in the January/February issue of Playboy magazine [Warning: link contains explicit language], which hits newsstands on December 18. "I mean, it's tastefully done. Steven Soderbergh directed it, and Michael Douglas plays Liberace. But this movie's not going to be for everyone."

Damon also said he and Douglas planned out scenes where the two display affection.

"For one scene, I had to come out of the pool, go over to Michael Douglas, straddle him on a chaise lounge and start kissing him," Damon said. "It's not like I kiss him just once. We drew it up like a football plan."

The 42-year-old actor also described Douglas as "a wonderful kisser."

Liberace, known for his flashy outfits as much as his music, never revealed his sexual orientation and successfully sued the UK tabloid The Mirror for implying he was gay in a 1956 article. Thorson served as the entertainer's bodyguard, chauffeur and confidant. Liberace was also linked romantically to women, including actress Mae West.

The movie will give viewers a "behind-the-scenes look at the tempestuous relationship between legendary entertainer Liberace and Scott Thorson, his younger live-in lover," producers said in a statement released by HBO Films last year, when the project was announced.

"Behind the Candelabra" does not have an official airdate but will air sometime in 2013. Damon will next be seen in "Promise Land" which also stars John Krasinski and hits theaters on January 4.

The actor, who wed his wife in 2005 and is a parent of four children with her, also reflected on his perception in the media.

"The narrative about me kind of goes, 'He's a boring married guy,' which is great, because I don't get any of that other stuff like Brad Pitt and George Clooney do," he said. "People think I'm kind of vanilla and they leave me alone to work, have an actual private life and be a husband and dad."

"When I turned 40 I had my whole family and some friends together. I realized I had to make a toast and hadn't thought of anything to say. I stood up, and what came to me seemed incredibly true in the moment and even more so as time has gone by," Damon later added. "I said, 'I think I might actually be the luckiest guy on earth. I really might be him.'"
